FOUNTAIN-PEN.

To all whom it may concern:

Be it known that I, JAMES W. CARLIN, a citizen of the United States,residing at Sandusky, in the county of Erie and State of Ohio, haveinvented certain new and useful Improvements in Fountain-Pens, of whichthe following is a specification.

This invention relates to fountain pens, and has for its object toprovide a fountain pen equipped with a valve which may be adjusted tovary the flow of ink to the pen point, and which will be so arranged asto cooperate with the cap of the pen, to hold the valve shut when thecap is in position, so that the pen may be placed in the pocket in anymanner, without spilling the ink.

Another object is to provide a pen having a valve of this character,which will be so arranged that the parts will be easy of access whenreplacement or repairs are necessary.

Other objects and advantages will be apparent from the followingdescription, and it will be understood that changes in the specificstructure shown and described may be made within the scope of the claimswithout departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts of the severalviews,Figure 1 is a longitudinal seetion through the valve portion ofthe pen, the valve being shown open. Fig. 2 is a section on line 22 ofFig. 1. Fig. 3 is a section through the pen with the cap in position,showing the end of the finger piece engaged in the cap slot, and thefinger of the cap engaged in the pen slot. Fig. 4 is a fragmentarysection, showing the cap partially on the pen.

Referring now to the drawings, there is shown a pen including areservoir handle 5, which is interiorly threaded at its open end asshown at 6. Acore? is threaded into this open end of the handle, andthis core is provided with a head 8, which corresponds in size with thereservoir handle, and which abuts against the outer end of the handle.The head-8 has in its outer face a recess. 9, which is provided with aninterior left hand thread, and screwed into this recess there is thereduced rearward end 10 of the forward end portion or feeder 11 of thepen, having a groove 12 for the reception of a pen nib 13, and having afeed finger 14,

which receives ink through a longitudinal passage 15 formed in theportion 11, and communicating with a passage 15 formed longitudinallythrough the core 7, this passage 15 opening through a beveled valve seat16 formed in the rearward face of the core, this valve seat surroundinga washer recess 17, which in turn surrounds the rearward end of acentral longitudinal passage 18 formed through the core. This passage 18communicates with and is disposed concentric to a recess 19 which isformed in the .rearward face of the reduced rearward extension 10 of theportion 11, and a radial slot 20 communicates with this recess 19 andopens through the outer face of the portion 11, as shown.

A cylindrical valve 21 has a bevel 22 which fits against a valve seat16, and this valve .21 has the groove 23 in its outer periphery whichmay be brought into and out of registration with the passage 15. In thisway the aperture of communication of this passage 15 with the inkreservoir may be varied or may be closed entirely as desired.

A rubber washer 24 is disposed in the recess 17 and the valve 21 carriesa longitudinal stem 25 which is engaged through the central passage 18,and which projects into the recess 19, where it has screwed thereupon ahead 26, which bears against a second rubber washer 27 engaged betweenthis head and the outer surface of the core 7, which surrounds thepassage 18, the two rubber washers efiectually preventing the leakage ofink through the passage 18, as will be understood.

The head 26 has a passage 28 formed radially therein and threaded, andthis passage receives the end of a threaded rod 29, extending throughthe radial passage 20, and having an outwardly extending end which formsa finger piece 30. This threaded rod bears against the threaded end ofthe stem 25 and thus prevents disengagement of the head 26 from thestem.

By engagement of the finger piece 30, the valve may be shifted to varythe flow of ink through the registering passages 15 and 15, as will beunderstood.

A longitudinal slot 31 is formed in the pen and receives a finger 32carried interiorly by the cap 33, this cap also having an interior capslot 34, which receives the finger piece 30, as will be understood. Therelative position of these elements is such that, when the finger 32 isin the slot 31, and the finger piece 30 is in the slot 34, the valve isin closed position, so that leakage of the pen while it is in the pocketis prevented.

What is claimed is:

1. In a fountain pen, the combination with a reservoir, a feederconnected with the reservoir, a pen nib connected with the feeder andmeans for feeding ink to the nib, of rotary means for varying the flowof ink to the feeder and for at times stopping the flow of the ink, anda cap for the pen, means on said cap for engagement with the ink varyingmeans when said means are in position to cut off the supply of ink andmeans on the cap for engagement with the pen nib, both of said cap meansbeing so arrangedthat the cap may be placed on the pen only when saidvarying means are closed.

2. A fountain pen comprising a reservoir, a core engaged in thereservoir, said core .to vary the flow of ink through the passage,

a stem carried by the valve, and extending through the core, a radialfinger piece connected with the stem and extending outwardly of thefeeder for swinging movement to shift the valve, a cap, and, pen nibengaging and finger engaging means on said cap, said valve engagingmeans being so arranged with relation to the pen nib engaging means thatsaid cap is prevented from application to the pen except when said valveis closed.

In testimony whereof I afiix my signature, in presence of two witnesses.
